US Spot Bitcoin ETFs Log $1.92B Weekly Inflows, Biggest Haul in 10 Months

US spot Bitcoin ETFs posted their strongest week of demand in nearly a year, drawing $1.92 billion of net inflows for the week ending August 22. The last comparable surge came in October 2025, when the group attracted $2.71 billion. The inflow burst coincided with Bitcoin gaining about 25% over the same period, lifting the token to near the $80,000 mark. All five sessions were positive for flows. Monday brought in $297.6 million, followed by $189.3 million on Tuesday. Inflows accelerated midweek with $517.2 million on Wednesday, peaked at $606.3 million on Thursday, then eased to $307.5 million on Friday. BlackRock's iShares Bitcoin Trust (IBIT) again took the largest share of demand, pulling in $503 million on the week's peak day. Fidelity's FBTC, Bitwise's BITB, and ARK 21Shares' ARKB also added meaningful contributions. Market drivers included expanded US Treasury buybacks during the week, which helped push yields lower and improved the relative appeal of risk assets. Short covering added momentum as Bitcoin rose, forcing bearish traders to repurchase positions and amplifying the move. Strength extended beyond Bitcoin. Ethereum spot ETFs recorded roughly $693 million to $697 million of inflows over the same window. Total assets under management across US spot Bitcoin ETFs have climbed to about $96 billion. The October 2025 weekly inflow record of $2.71 billion remains the benchmark. US spot Bitcoin ETFs have traded since January 2024. Following outflows earlier in 2026—including an eight-week losing streak that ended in July—the latest figures point to a sharp rebound in investor confidence.
